FANNlNG-MILL.

SPECIFICATION forming part of Letters Patent No. 321,270, dated June 30,1885.

- Application filed November 20, 1884. (No model.)

To all whom it may concern.-

Be it known that we, THOMAS M. BALES and CHARLES P. RILEY, citizens ofthe United States, residing at Oonnersville, in the county of Fayetteand State of Indiana,have invented certain new and useful Improvementsin Fanning-Mills; and we do declare the .following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

Figure 1 of the drawings is a side View of a fanning-mill embodying ourimprovements. Fig. 2 is a plan view. Fig. 3 is a vertical centralsectional view. Fig. 4 is a view of the fan and fan-shaft detached fromthe machine, and of the eccentric and the connecting-rod. Fig. 5 is afront view.

This invention relates to improvements in fanning-mills for separatingditferentkinds of grain or seeds; and it consistsin the construetion andarrangement of parts, fully described in the annexed specification andpointed out in the claims thereof.

Referring to the accompanying drawings and the letters of referencemarked. thereon, A represents the frame of the machine, of the usualshape, and having attached thereto the hopper B and the upper and lowershoes or screen-frames, O and D, respectively.

a is the main or actuating shaft of the machine, turning in properbearings fixed to the frame, as shown. The shaft a is rotated by meansof the gear-Wheels E, e, e, and e and the crank-handle c,0r by otherproper mechanism.

F is an eccentric fixed on the shaft a and reciprocating theeccentric-rod 0*, fixed at its front end to the eccentric-strap, and atits rear end loosely connected to the rear of the upper shoe, 0, asshown.

G is the fan, fixed to and rotating with the shaft a, and composed ofthe blades 9 divided centrally for the passage of the rod 6*. The bladesform, in fact, two similar equal sets on each side of the eccentric.

H H are vibrating straps pivoted at their ing the lower shoe outwardwhen it has been reciprocated inwardly.

J J are the iron straps, pivoted by their upper ends to the hopper oneach side, and by their lower ends to the front corners of the uppershoe. These straps support the front end of the upper shoe.

K K are similar straps, connecting the lower shoe near its corners withthe front of the main frame, and act in a corresponding manner to theupper shoe. is are pins to adjust the straps higher or lower.

The shoes, besides being reciprocated by their straps, have also atossing motion imparted to them,as thestraps J and Kare short er thanthe arms of the straps H, and consequently lift the ends of the shoeswhen extended. The grain is thus tossed and evenly spread in passingover the screens and prevented from clogging in the meshes.

L L are knockers attached to each side of the main frame below the lowershoe near its center in such manner that they will strike against thelatter when it is reciprocated and will jar the screen.

The upper shoe, C, consists of a frame inclining downward toward therear end of the machine from the hopper, and having attached to it avery fine screen, 0. This screen is too fine for grain to pass through,and as the latter passes over it the blast lifts the chaff and dustclear of the grain.

c is a transverse strip of tin-plate secured within the rear lower endof the frame 0 and inclining inward and downward therefrom.

M is the screen or screens of the upper shoe, having a transverse barunder the hopper about six inches wide, so that the grain slides offwhen dropping from the hopper, and the sticks and straw joints cannotfall upon and stick in the meshes.

N N are the screens of the lower shoe, D, the upper coarser than thelower one, as usual, and intended to deliver, by the opening N, numberone grade of wheat, while the lower screen delivers number two grade bythe opening N. In cleaning small seed the upper screen delivers cloverand the lower screen timothy seed.

0 is an opening in the floor of the lower shoe for the delivery of thescreenings.

P is a wind-board pivoted or hinged at its lower edge to the main frameat a point corresponding to and a short distance in front of the lowestpoint of the fan, and R is a windboard pivoted at the center of its sideedges in the main frame vertically above P. This board R is providedwith a longitudinal slot, a, for the passage of the rod 6*. By means ofthese boards the blast can be cut oil from the upper shoe or can bedirected upward upon any point of said shoe at pleasure.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

lower screen-frame to the main frame, and

means for vertically jarring the screens, substantially as specified.

2. In a fanning-mill, the combination, with the main frame, the upperand lower screens, the drive-shaft, and divided fan, of the eccentric F,rod e, wind-board 1?, adapted to be adj ustably supported with relationto the fan, as shown, and the wind-board R, pivoted and slotted for thereception of the said rod, whereby the direction of the blast may be cutoil or varied upon the upper screen, substantially as specified.

In testimony whereof we aflix our signatures in presence of twowitnesses.
